A recent study reveals that large-scale carbon removal strategies, such as tree planting, can conflict with biodiversity conservation. While these strategies are essential to meet climate goals, careful planning is necessary to avoid harming critical ecosystems, particularly in biodiversity hotspots and climate refugia areas.

The urgency to combat climate change necessitates significant carbon dioxide emission reductions and the implementation of large-scale carbon removal strategies. A recent study examined the relationship between these strategies and biodiversity conservation, revealing potential conflicts. For instance, planting trees in ecosystems like savannas can disrupt habitats. However, with careful planning, carbon removal efforts can also benefit biodiversity, such as through forest restoration in degraded areas. The study emphasizes the importance of biodiversity hotspots and climate refugia, which are crucial for preserving species as climate change progresses. It found that up to 13% of global climate refugia might be affected by land-intensive carbon removal methods. Moreover, enforcing biodiversity protection could render over 50% of designated carbon removal land unavailable, necessitating alternative approaches. Ultimately, the research advocates for tailored carbon removal strategies that consider local ecosystems to balance climate action and biodiversity preservation.
